@ Pterist "... just copies of copies of copies of many documents from that period."
I watched this video from Professor Bart Dr. Ehrmann on youtube:

I found this link in another thread here in the forum. For me it was very enlightening.
He explained:
- " just copies of copies of copies of copies of copies..." and
- why the scribes changed there copy and
- why every copy was different from the copy before and
- why in all copies are more differences as words in the bible and
- why he tells his students, to read the gospels horizontally and not only vertically and a lot more.
